Google unveils the Chrome extension "Password Checkup" for free, warning the use of leaked passwords

If you use leaked login information, issue a warning and prompt to change the password

　On February 5th (local time), Google released its extended function "Password Checkup" for "Google Chrome" for free. Check whether the login information you entered in the browser is leaked to a third party, notify it if there is any data infringement, and urge you to change your password.

　In the case of a "Google account", the password will be automatically reset as soon as a password leak or abuse is detected. It is reported that, thanks to this mechanism, the risk of an account being hacked is controlled at the usual 1x10. However, only Google accounts can be protected through this mechanism.

　"Password Checkup" is an extension designed to apply the account protection mechanism in Google account so that other services can detect data infringement as soon as possible. It is said that more than 4 billion accounts confirm that login information has been compromised, and "Password Checkup" will issue a warning if the combination of ID and password entered is consistent with such leaked data.

　The password checking mechanism used in this extension was developed with the assistance of Stanford University, and identification information about accounts, passwords and devices will not be reported to Google during diagnostics. While maintaining privacy, security can be improved.
